THE TERMAL DEFORMATION OF ISOTROPIC BEAM ELEMENTS OF TECHNOLOGICAL EQUIPMENT IN THE MANUFACTURING OF CARBON-CARBON COMPOSITE MATERIALS IN FURNACES OF DIRECT HEATING

For the isotropic beam elements of the technological equipment (BETE), which are used in the production of carbon-carbon composite materials (CCCM) in direct heating furnaces, the analytical solution of the temperature stress-strain state, taking into account the stiffness of the spring of the current collector, was obtained for the first time in the work. Formulas for calculating the critical diameters of loss of compressive strength are given. Using the example of graphite and molybdenum rods, it was established in the work that the decisive factor of the load-bearing capacity is the loss of stability of the elements under consideration.
